:祈使句,and/ then/or +一般將來時(shí)的簡單句。其中“or”解釋為“否則”,“and/then”解釋為“然后”,根據(jù)句意選擇D?!纠?】We should leave early tomorrow morning,________ we won39。t get there on time.A. so B. but C. or D. and【解析】答案是C。連詞or在句中表示“否則,不然”,轉(zhuǎn)折所導(dǎo)致的結(jié)果;so表示結(jié)果;前后對(duì)應(yīng),and是并列關(guān)系的連詞;but表示轉(zhuǎn)折與上文相反?!纠?】Bill won39。t make any progress ________ he studies harder than before. A. so B. when C. because D. unless【解析】答案是D。根據(jù)句意結(jié)果是不會(huì)取得進(jìn)步,四個(gè)選項(xiàng)的關(guān)系so所以,表示結(jié)果;when當(dāng)……時(shí)候,表示時(shí)間;because因?yàn)?;unless如果不,除非,表示條件?!纠?】________ Tom ________ Mary is busy at the moment. You39。d better play with others.A. Both。 and B. Not only。 but alsoC. Neither。 nor D. Either。 or【解析】本題答案是B。首先根據(jù)動(dòng)詞is busy單數(shù)形式可排除A選項(xiàng)動(dòng)詞用復(fù)數(shù)。根據(jù)下文意思分析,此刻兩個(gè)人都很忙,不能和你玩。而C選項(xiàng)是否定意義,兩個(gè)人都不忙,D選項(xiàng)表示兩個(gè)人中有一個(gè)人忙,可以和你玩。這是極容易錯(cuò)的典型題。【例6】The cyclist held his raincoat tightly ________ the wind couldn39。t blow it away. A. so B. so that C. when D. because【解析】本題答案是B。首先要考慮上下文的關(guān)系,不是因果關(guān)系,所以排除A和D。緊緊抓住雨衣目的是為了防止刮走,而C是表示時(shí)間的連詞?!纠?】Peter was late for the meeting ________ he missed the ferry. A. though B. because C. while D. if【解析】答案是B。本句上下文是因果關(guān)系,上句是結(jié)果,下句表示原因,故用because。四個(gè)選項(xiàng)都是引導(dǎo)狀語從句的從屬連詞而不是并列連詞。though是轉(zhuǎn)折關(guān)系的從屬連詞;while用來表示轉(zhuǎn)折關(guān)系;if表示假設(shè)的條件,不符合句意?!纠?】 Which would you like to buy,a DVD player ________ an MP3 player? A. so B. or C. but D.a(chǎn)nd【解析】答案是B。本句是選擇疑問句,是“特殊疑問句,A or B?”結(jié)構(gòu)。提供兩種情況,詢問對(duì)方選擇哪一種。【例9】Mr. Li is our teacher and friend as well.(保持句意基本不變)Mr. Li is ________ only our teacher ________ also our friend. 【解析】答案是not only…but also。根據(jù)句意,as well是“也是”的意思,而not only...but also是固定詞組,表示“不僅……而且”,與句意吻合。三、學(xué)法提煉1. 專題特定:連詞是選擇,完形中常考。熟練地連詞使用,對(duì)寫作也有提升。2. 解題方法:連詞看似簡單實(shí)則易錯(cuò)。特別要提醒同學(xué)注意的是必須掌握每個(gè)連詞的用法,認(rèn)真仔細(xì)地思考、分析和判斷,這樣才能從四個(gè)選項(xiàng)中通過排除三個(gè)錯(cuò)誤的選項(xiàng)選出正確答案。杜絕有些同學(xué)沒有經(jīng)過完整的思考,題目只讀到一半的時(shí)候就填寫答案。3. 注意事項(xiàng):注意使用連詞后,哪些謂語動(dòng)詞用單數(shù),哪些用復(fù)數(shù)。課后作業(yè)作業(yè)1:整理錯(cuò)題作業(yè)2:單項(xiàng)選擇1.
